l-e it known that we, (inonde FUnNnss and .l1-mns Ronnnrsuixw, both ot the city of Manchester, in the county of Lancaster, England,

5 have invented an Improvement 1in Curtain-- O a stud and projecting boss having a slot therein to receive one end oi" a cord. The said boss abuts against the said metallic disk when fixed in position. The said boss is also formed with recesscsvhich receive the screws employed to connect the said ratchet or star wheel with the said disk and roller. The said stud or pin of' the star or ratchet wheel is supported by a metal bracket. The bracket (usually mounted on the right of the roller when iii position) is 3@ east or formed with a suitably-shaped slot, in which slot said ratchet-wheel stud is permitted to roll to and fro when the blind is acted up on. rllhe said bracket is also cast with a guide-eye, through which the cord from the boss passes, the object being to prevent the cord overriding the boss up on which it is wound. The bracket is also cast or formed with a projecting stud or pin, against which a tooth ot' the ratchetwheel comes in contact when it is required to 40 stop the blind in any desired position.

In the drawings, Figure l is a front View of a roller embodying our invention. Fig. 2 is aA plan of same in position l'or raising the blind or curtain, or to allow the same to be lowered. Fig. 3 represents the blind-roller detached, with the ends thereoil in section, and shows more clearly the manner of connecting the disks and ratchet-wheel to the end ofthe roller. Fig. 4L represents the bracket for supporting the 5o stud in the end ofthe roller. Fig. 5 represents To one end ofthe said roller a charts, or other analogous articles.

the raiehet-wheel when disengaged. Fig. G represents the manner ol" connecting the end' ol' the cord to the boss of the ratchet-wheel. Fig. '7 represents a side view ot' the ratchetwheel, boss, and screws for fastening the saine to the end ot' the roller. Fig. S represents a side view of the metal disk 'screwed onto `end oi" roller, and against which the boss ol' ratchet-wheel abuts. Fi 9 represents a plan of the same.

The blind or curtain A is attached tothe roller B in any suitable manner. To the ends ot' the said roller l metal clips C and l) are secured e by means oi'screws. The ratchet-wheelE,hav ing in this example live teeth, is cast with a boss,l`., which abnts against the end of the rollen, as seen in Fig. 5i, being held by means of screws which lie in the grooves or recesses formed on the periphery oi' the boss, wheijeby an even cylindrical surface is obtained. The bracket J is cast or formed with a projection, G, and with a slot, K. rFhe blind,`when free to run down or unwind from the roller, causes the said roller to advance in the slot K toward projection G, which action brings one or the 7 5 other of the ratchet-teeth into contact with said projection Gr, and the further unwinding ofthe blind is instantly arrested. rlhc said bracket J is also cast with a shoulder having formed therein an eye, L, intowhich an eyel et is iitted to reduce friction of the cord l. The manner of connecting the cord with the boss of the ratchet-wheel is seen more clearly in Fig. 6, in which it will be seen that the boss is split to receive and hold a knot formed on the end of the cord. The blind can be lowered to any desired extent by action of the cord, which is so arranged that when slightly pulled it causes the stud M to slide in the slot IQ and the ratchet-teeth to move ont of contact with the projection G, and the blind is free to unwind. Vhen the cord is liberated,the rotation of the roller causes the stud M to advance in the slot, which action brings one or the other of the ratchet-teeth in contact with the projection G, and the further unwindingof the blind is instantly arrested. It will be readily understood that the appliances are equally applicable to the raising, holding, or lowering of maps, plans,A

Thile We have described a specific construction, even to small details,we do not limit ourselves to such, as our invention may be modiiied in various ways Without departing` from the novelty and utility of the same.

We are aware of the patents to Brothwell, December 6, 1870, and Barrett and Knight, October 21, 1879, and claim nothing therein set forth or shown.

Having now described our invention, what we claim as new, and desire to secure by Letters Patent, is-

1. A roller for curtains, maps, Src., loosely supported in bearings and adapted to be shifted horizontally, in combination with means to ro-- tate said roller and shift the same, and a stationary locking device to prevent the rotation of the roller when shifted in one direction and free it When shifted in the other direction.

2. A roller for curtains, maps, &c., loosely supportedin bearings, one end of which is arranged to slide in a horizontal slot, in combination. witha stationary cord-guide, a cord to rotate said rollervand cause it to be shifted to one end of said slot, ablind, curtain, map, 81e., so Wound upon said roller as to cause it to be rotated and move to the other end of said slot, and a stationary locking,` device to prevent the rotation of said roller when the same is at one l end of the slot, substantially as and for the 3o purpose specified.

3. The combination of roller B, brackets to support the same, iianged boss F, having stud M, screws F', and cord I, substantially as and for the purpose specified.

et. The combination of roller B, brackets J, one of which has a slot, K, and projection G, cord I, and ratchet-Wheel E, secured to the end of the roller, substantially as and for the purpose specified.

5. The combination of roller B, provided on one end with boss F, having ratchet-Wheel E and stud M, supporting -brackets J, one of which has a slot, K, and projection G, and cord I, substantially as set forth.

6. The combination of roller B, provided on one end With a ratchet-Wheel, E, and stud M,

supporting-brackets J, one of which has a slot,
